Description
This command is the string that
the DataHub sends to all clients when a point value changes (i.e. a
point exception occurs). The DataHub also listens for a
point command because this is the mechanism
that it uses to get updates from another DataHub that it is
mirroring. This is not a command that a user would normally emit.
Point changes should be sent to the DataHub using the write or cwrite
commands.
